Consolidated price level expansion

ABSTRACT

Certain embodiments provide consolidated price level expansion. Data associated with the individual price levels represented by a consolidated price level is expanded and provided through an expanded consolidated price level interface. In certain embodiments, the expanded consolidated price level interface includes a pop-up interface. In certain embodiments, the expanded consolidated price level interface includes an in-line interface. In certain embodiments, an order may be entered using the expanded consolidated price level interface.

BACKGROUND

The presently described technology is directed towards electronictrading systems. More particularly, certain embodiments are directedtowards consolidated price level expansion in a trading interface.

An electronic trading system generally includes a client device incommunication with an electronic exchange that may serve as a host forthe client device. Typically, the electronic trading system provides forelectronically matching orders to buy and sell tradeable objects to betraded. A tradeable object is an item that may be traded. Stocks,options, futures contracts, securities, and commodities are a fewexamples of tradeable objects.

The electronic exchange transmits market data to the client device. Themarket data may include, for example, price data, market depth data,last traded quantity data, data related to a market for the tradeableobject, and/or combinations thereof. The client device receives marketdata from the electronic exchange.

In some electronic trading systems, a client device receives andprocesses market data without displaying the market data on a displaydevice. However, in other electronic trading systems, the client devicedisplays processed market data on a display device. The client devicemay include software that creates a trading screen. In general, atrading screen enables a user to participate in an electronic tradingsession. For example, a trading screen may enable a user to view marketdata, submit a trade order to the electronic exchange, obtain a marketquote, monitor a position, and/or combinations thereof.

In some electronic trading systems, the client device sends trade ordersto the electronic exchange. However, in other electronic tradingsystems, other devices, such as server side devices, are responsible forsending the one or more trade orders to the electronic exchange. Uponreceiving a trade order, the electronic exchange enters the trade orderinto an exchange order book and attempts to match quantity of the tradeorder with quantity of one or more contra-side trade orders. By way ofexample, a sell order is contra-side to a buy order with the same price.Similarly, a buy order is contra-side to a sell order with the sameprice. Unmatched quantity of a trade order is held in the exchange orderbook until quantity of a trade order is matched by the electronicexchange. Unmatched quantity of a trade order may also be removed fromthe order book when a trade order is cancelled, either by the clientdevice or electronic exchange. Upon matching quantity of the tradeorder, the electronic exchange may send a confirmation to the clientdevice that the quantity of the trade order was matched.

A trading screen may display a number of price levels and theoutstanding bid or ask quantities corresponding to those price levels.While the market may include outstanding bid and ask quantities at amultitude of different price levels, the trading screen may not bephysically large enough (and/or a trader may not want to provide enoughscreen area) to accommodate displaying all of the different price levelsand their outstanding bid or ask quantities. Thus, a trading screentypically displays a range of price levels (and the correspondingoutstanding quantity) around the inside market.

However, displaying a small range of price levels around the insidemarket may provide a trader with a narrow view of the market. The tradermay view the market depth around the inside market, but the trader maynot be able to see the outstanding market depth at price levels furtheraway from the inside market.

DETAILED DESCRIPTION I. Example Electronic Trading System

FIG. 1 illustrates a block diagram of an electronic trading system 100in which certain embodiments may be employed. The system 100 includes aclient device 110, a gateway 120, and an electronic exchange 130. Theclient device 110 is in communication with the gateway 120. The gateway120 is in communication with the exchange 130.

As used herein, the phrase “in communication with” may include in directcommunication and indirect communication through one or moreintermediary components.

In operation, the client device 110 may send orders to buy or selltradeable objects at the exchange 130. For example, a user may utilizethe client device 110 to send the orders. The orders are sent throughthe gateway 120 to the exchange 130. In addition, market data is sentfrom the exchange 130 through the gateway 120 to the client device 110.The user may also utilize the client device 110 to monitor this marketdata and base a decision to send an order for a tradeable object on themarket data.

A tradeable object is anything which can be traded with a quantityand/or a price. For example, financial products such as stocks, options,bonds, futures, currency, warrants, funds derivatives, securities,commodities, traded events, goods, and collections and/or combinationsof these may be tradeable objects. A tradeable object may be “real” or“synthetic.” A real tradeable object includes products that are listedby an exchange. A synthetic tradeable object includes products that aredefined by the user and are not listed by an exchange. For example, asynthetic tradeable object may include a combination of real (or othersynthetic) products such as a synthetic spread created by a traderutilizing a client device 110.

The client device 110 may include one or more electronic computingplatforms such as a hand-held device, laptop, desktop computer,workstation with a single or multi-core processor, server with multipleprocessors, and/or cluster of computers, for example.

The client device 110 is generally owned, operated, controlled,programmed by, configured by, or otherwise used by a user. As usedherein, the phrase “user” may include, but is not limited to, a human(for example, a trader) or an electronic trading device (for example,including a processor and memory or an algorithmic trading system). Oneor more users may be involved in the ownership, operation, control,programming, configuration, or other use, for example.

The client device 110 may include one or more trading applications. Thetrading application(s) may, for example, process market data byarranging and displaying the market data in trading and chartingwindows. This processing may be based on user preferences, for example.The trading application(s) may include an automated trading tool such asan automated spread trading tool, for example.

The client device 110 may include an electronic trading workstation, aportable trading device, an algorithmic trading or “black-box” system,an embedded trading system, and/or an automated trading tool, forexample. For example, the client device 110 may be a computing systemrunning a copy of X_TRADER®, an electronic trading platform provided byTrading Technologies International, Inc. of Chicago, Ill. As anotherexample, the client device 110 may be a computing device running anautomated trading tool such as Autospreader® and/or Autotrader™, alsoprovided by Trading Technologies International, Inc.

The client device 110 is adapted to send orders to buy or sell atradeable object. The client device 110 may also be adapted to cancelorders, change orders, and/or query an exchange, for example.

The orders sent by the client device 110 may be sent at the request of auser or automatically, for example. For example, a trader may utilize anelectronic trading workstation to place an order for a particulartradeable object, manually providing various parameters for the ordersuch as an order price and/or quantity. As another example, an automatedtrading tool may calculate one or more parameters for an order andautomatically send the order. In some instances, an automated tradingtool may prepare the order to be sent but not actually send it withoutconfirmation from the user.

In certain embodiments, the client device 110 includes a user interface.The user interface may include one or more display devices forpresenting a text-based or graphical interface of a trading applicationto a user, for example. For example, the display devices may includecomputer monitors, hand-held device displays, projectors, and/ortelevisions. The user interface may be used by the user to specify orreview parameters for an order using a trading application. The userinterface may include one or more input devices for receiving input froma user, for example. For example, the input devices may include akeyboard, trackball, two or three-button mouse, and/or touch screen. Theuser interface may include other devices for interacting with a user.For example, information may be aurally provided to a user through aspeaker and/or received through a microphone.

In certain embodiments, a trading application may include one or moretrading screens to enable a trader to interact with one or more markets.Trading screens may enable traders to obtain and view marketinformation, set order entry parameters, enter and cancel orders, and/ormonitor positions while implementing various trading strategies, forexample. For example, a trading application may receive information(such as bid prices, bid quantities, ask prices, ask quantities, pricesand quantities for past sales, and/or other market related information)from exchange 130 which, in turn, may be displayed with a user interfaceof client device 110. Based on the received information, the tradingscreen may display a range of price levels and corresponding bid and askquantities for the price levels in regard to tradeable objects. In orderto provide the trader with pertinent trading information, the tradingscreen may display a range of prices (and the corresponding bid and askquantities) around the inside market. The information may becontinuously or regularly provided to the trading application, whichallows the trading application to update the trading screen with currentmarket information. A trader may use the trading screen to place buy andsell orders for tradeable objects or to otherwise trade the tradeableobjects based on the displayed information, for example.

Trading screens may display one or more trading tools. Trading tools areelectronic tools that allow, assist with, and/or facilitate electronictrading. Exemplary trading tools include, but are not be limited to,charts, trading ladders, order entry tools, automated trading tools,automated spreading tools, risk management tools, order parameter tools,order entry systems, market grids, fill windows, and market orderwindows, combinations thereof, other electronic tools used for trading,preparing to trade, or managing trades.

In certain embodiments, the orders from the client device 110 are sentto the exchange 130 through the gateway 120. The client device 110 maycommunicate with the gateway 120 using a local area network, a wide areanetwork, a virtual private network, a T1 line, a T3 line, an ISDN line,a point-of-presence, and/or the Internet, for example.

The gateway 120 is adapted to communicate with the client device 110 andthe exchange 130. The gateway 120 facilitates communication between theclient device 110 and the exchange 130. For example, the gateway 120 mayreceive orders from the client device 110 and transmit the orders to theexchange 130. As another example, the gateway 120 may receive marketdata from the exchange 130 and transmit the market data to the clientdevice 110.

In certain embodiments, the gateway 120 performs processing on datacommunicated between the client device 110 and the exchange 130. Forexample, the gateway 120 may process an order received from the clientdevice 110 into a data format acceptable by the exchange 130. Similarly,the gateway 120 may transform market data in an exchange-specific formatreceived from the exchange 130 into a format understood by the clientdevice 110. The processing of the gateway 120 may also include trackingorders from the client device 110 and updating the status of the orderbased on fill confirmations received from the exchange 130, for example.As another example, the gateway 120 may coalesce market data from theexchange 130 and provide it to the client device 120.

In certain embodiments, the gateway 120 provides services other thanprocessing data communicated between the client device 110 and theexchange 130. For example, the gateway 120 may provide risk processing.

The gateway 120 may include one or more electronic computing platformssuch as a hand-held device, laptop, desktop computer, workstation with asingle or multi-core processor, server with multiple processors, and/orcluster of computers, for example.

The gateway 120 may include one or more gateway applications. Thegateway application(s) may, for example, handle order processing andmarket data processing. This processing may be based on userpreferences, for example.

In certain embodiments, the gateway 120 communicates with the exchange130 using a local area network, a wide area network, a virtual privatenetwork, a T1 line, a T3 line, an ISDN line, a point-of-presence, and/orthe Internet, for example.

In general, the exchange 130 may be owned, operated, controlled, or usedby an exchange entity. Exemplary exchange entities include the LondonInternational Financial Futures and Options Exchange (“LIFFE”), theChicago Board of Trade (“CBOT”), and the Chicago Mercantile Exchange(“CME”). The exchange 130 may be an electronic matching system, such asa computer, server, or other computing device, that is adapted to allowtradeable objects, for example, offered for trading by the exchange, tobe bought and sold.

The exchange 130 is adapted to match orders to buy and sell tradeableobjects. The tradeable objects may be listed for trading by the exchange130. The orders may include orders received from the client device 110,for example. Orders may be received from the client device 110 throughthe gateway 120, for example. In addition, the orders may be receivedfrom other devices in communication with the exchange 130. That is,typically the exchange 130 will be in communication with a variety ofother client devices (which may be similar to client device 110) thatalso provide orders to be matched.

The exchange 130 is adapted to provide market data. The market data maybe provided to the client device 110, for example. The market data maybe provided to the client device 110 through the gateway 120, forexample. The market data may include data that represents the insidemarket, for example. The inside market is the lowest sell price (alsoreferred to as the “best ask”) and the highest buy price (also referredto as the “best bid”) at a particular point in time. The market data mayalso include market depth. Market depth refers to the quantitiesavailable at the inside market and may also refer to quantitiesavailable at other prices away from the inside market. Thus, the insidemarket may be considered the first level of market depth. One tick awayfrom the inside market may be considered the second level of marketdepth, for example. In certain embodiments, market depth is provided forall price levels. In certain embodiments, market depth is provided forless than all price levels. For example, market depth may be providedonly for the first five price levels on either side of the insidemarket. The market data may also include information such as the lasttraded price (LTP), the last traded quantity (LTQ), and order fillinformation.

In certain embodiments, the system 100 includes more than one clientdevice 110. For example, multiple client devices similar to the clientdevice 110, discussed above, may be in communication with the gateway120 to send orders to the exchange 130.

In certain embodiments, the system 100 includes more than one gateway120. For example, multiple gateways similar to the gateway 120,discussed above, may be in communication with the client device 110 andthe exchange 130. Such an arrangement may be used to provide redundancyshould one gateway 120 fail, for example.

In certain embodiments, the system 100 includes more than one exchange130. For example, the gateway 120 may be in communication with multipleexchanges similar to the exchange 130, discussed above. Such anarrangement may allow the client device 110 to trade at more than oneexchange through the gateway 120, for example.

In certain embodiments, the system 100 includes more than one exchange130 and more than one gateway 120. For example, multiple gatewayssimilar to the gateway 120, discussed above, may be in communicationwith multiple exchanges similar to the exchange 130, discussed above.Each gateway may be in communication with one or more differentexchanges, for example. Such an arrangement may allow one or more clientdevices 110 to trade at more than one exchange (and/or provide redundantconnections to multiple exchanges), for example.

In certain embodiments, the client device 110 includes one or morecomputing devices or processing components. In other words, thefunctionality of the client device 110 may be performed by more than onecomputing device. For example, one computing device may generate ordersto be sent to the exchange 130 while another computing device mayprovide a graphical user interface to a trader. In certain embodiments,the gateway 120 includes one or more computing devices or processingcomponents. In other words, the functionality of the gateway 120 may beperformed by more than one computing device. In certain embodiments, theexchange 130 includes one or more computing devices or processingcomponents. In other words, the functionality of the exchange 130 may beperformed by more than one computing device.

In certain embodiments, the gateway 120 is part of the client device110. For example, the components of the gateway 120 may be part of thesame computing platform as the client device 110. As another example,the functionality of the gateway 120 may be performed by components ofthe client device 110. In certain embodiments, the gateway 120 is notpresent. Such an arrangement may occur when the client device 110 doesnot need to utilize the gateway 120 to communicate with the exchange130, for example. For example, if the client device 110 has been adaptedto communicate directly with the exchange 130.

In certain embodiments, the gateway 120 is physically located at thesame site as the client device 110. In certain embodiments, the gateway120 is physically located at the same site as the exchange 130. Incertain embodiments, the client device 110 is physically located at thesame site as the exchange 130. In certain embodiments, the gateway 120is physically located at a site separate from both the client device 110and the exchange 130.

While not shown for the sake of clarity, in certain embodiments, thesystem 100 may include other devices that are specific to thecommunications architecture such as middleware, firewalls, hubs,switches, routers, exchange-specific communication equipment, modems,security managers, and/or encryption/decryption devices.

The components, elements, and/or functionality of the system 100discussed above may be implemented alone or in combination in variousforms in hardware, firmware, and/or as a set of instructions insoftware, for example. Certain embodiments may be provided as a set ofinstructions residing on a computer-readable medium, such as a memory,hard disk, CD-ROM, DVD, and/or EPROM, for execution on a general purposecomputer or other processing device.

II. Price Consolidation

As noted above, displaying a small range of price levels around theinside market may provide a trader with a narrow view of the market. Thetrader may view the market depth around the inside market, but thetrader may not be able to see the outstanding market depth at pricelevels further away from the inside market because, for example, thetrading screen may not be physically large enough (and/or a trader maynot want to provide enough screen area) to accommodate displaying all ofthe different price levels and their outstanding bid or ask quantities.

This problem may be accentuated depending on the “tick” size used by themarket or the client software. A tick generally refers to the smallesttradeable price level graduation in the market. A market may use anymeasure for a tick. For example, a tick may represent a fraction of adollar or another currency. As another example, a tick may represent adecimal portion of a dollar or another currency. When displaying smallerticks, the trading screen displays an increasingly narrow view of thecurrent market. For example, using a graduation of one cent, a tradermay only be able to see price levels a few cents away from the insidemarket. The market, however, may have bids and asks outstanding over arange of several dollars away from the inside market, but the trader maynot be able to see these other outstanding bids and asks due to thenarrow range of price levels within the viewable area of the tradingscreen.

One technique to allow a trader to see a wider range of price levels isprice consolidation. Exemplary trading screens that implement priceconsolidation are described in U.S. Pat. No. 7,127,424, entitled “ClickBased Trading With Intuitive Grid Display of Market Depth and PriceConsolidation,” filed on Oct. 5, 2001; U.S. Pat. No. 7,389,268, entitled“Trading Tools for Electronic Trading,” filed on Apr. 19, 2002; and U.S.Pat. No. 7,577,602, entitled “Method and Interface for ConsolidatingPrice Levels on a Trading Screen,” filed on Nov. 26, 2002, both of whichare herein incorporated by reference in their entirety.

In price consolidation, two or more price levels may be combined into asingle “consolidated” price level. That is, the consolidated price levelrepresents two or more price levels. Data related to the individualprice levels of the consolidated price level may be combined to obtainconsolidated data for the consolidated price level. For example, theconsolidated price level data may include a consolidated bid or askquantity that may be the sum of the outstanding quantities of theun-consolidated price levels combined to form the consolidated pricelevel. Using price consolidation, a trading screen may then displayinformation from a greater number of price levels on the trading screenthan it would be able to if it did not use price consolidation.

FIG. 2A illustrates a trading interface 200 with un-consolidated pricelevels. The trading interface 200 includes a price column 210, a bidquantity column 220, and an ask quantity column 230. The total quantityavailable to buy or sell at each price level along the price column 210is shown in the respective bid column 220 and ask column 230.

FIG. 2B illustrates a trading interface 250 with un-consolidated pricelevels. The trading interface 250 includes a market grid with a bidprice column 260, an ask price column 270, a bid quality column 280, andan ask quality column 290. The quantity available to buy at each pricelevel along the bid price column 260 is shown in the bid quantity column280. The quantity available to sell at teach price level along the askprice column 270 is shown in the ask quantity column 290.

FIG. 2C illustrates the trading interface 200 shown in FIG. 2Aindicating the price levels to be grouped using a price consolidationtechnique similar to an embodiment discussed in U.S. Pat. No. 7,127,424,referenced and incorporated above. Note that other groupings and/orother price consolidation techniques may be utilized to achieve a priceconsolidated display, as understood in the art.

FIG. 3A illustrates a trading interface 300 with consolidated pricelevels in which certain embodiments may be employed. More particularly,the trading interface 300 corresponds to the trading interface 200 withprice consolidation applied according to the groupings illustrated inFIG. 2C.

The trading interface 300 includes consolidated price level data 310 forconsolidated price level 106700. The consolidated price level data 310includes the consolidated price level 311 (106700), the consolidated bidquantity 312 (197), the consolidated ask quantity 313 (0), and theconsolidated working order data 314 (no working orders are present inthis example).

FIG. 3B illustrates a trading interface 350 with consolidated pricelevels in which certain embodiments may be employed. More particularly,the trading interface 350 corresponds to the trading interface 250 withprice consolidation applied according to the groupings illustrated inFIG. 2C.

The trading interface 350 includes consolidated price level data that isdifferent for the consolidated price levels based on whether they haveconsolidated bid quantity available or consolidated ask quantityavailable. In the former case, the consolidated price level dataincludes the consolidated bid quantity and the consolidated price level.In the latter case, the consolidated price level data includes theconsolidated price level and the consolidated ask quantity.

III. Expansion of a Consolidated Price Level

Certain embodiments provide consolidated price level expansion. In atrading interface including a consolidated price level, data associatedwith the individual price levels represented by the consolidated pricelevel is expanded and provided through an expanded consolidated pricelevel interface.

In certain embodiments, the expanded consolidated price level interfaceincludes a pop-up interface. The pop-up interface may be a window orgraphical object, for example. The pop-up interface may be displayedsuch that it appears to overlay at least in part, be on top of, or be infront of some or all of a trading interface, for example. Alternatively,the pop-up interface may be displayed in a screen region that does notoverlap a trading interface.

In certain embodiments, the expanded consolidated price level interfaceincludes an in-line interface. The in-line interface extends or replacesthe consolidated price level being expanded. The in-line interface isdisplayed such that it appears to be (or is) an integrated part of atrading interface.

An expanded consolidated price level interface is generated in responseto a command from a user. The expanded consolidated price levelinterface is generated for one or more consolidated price levels. Forexample, the expanded consolidated price level interface may begenerated for a price level associated with the command. As anotherexample, the expanded consolidated price level interface may begenerated for a consolidated price level associated with the location ofa cursor and two adjacent consolidated price levels.

The expanded consolidated price level interface is generated based onsome or all of the data associated with the price levels represented bythe consolidated price level to be expanded, as discussed in more detailbelow.

The generated expanded consolidated price level interface is thendisplayed. As discussed above, the expanded consolidated price levelinterface may be a window or graphical object and may appear to be (orbe) an integrated part of a trading interface.

The command may be an input from a user input device. For example, theinput may include a key press, mouse movement, mouse click, or tap on atouch screen.

For example, the expanded consolidated price level interface may begenerated and then displayed in response to a user pressing a key on akeyboard.

As another example, the expanded consolidated price level interface maybe generated and then displayed in response to a user clicking a middlemouse button while a cursor is positioned in a region or area associatedwith a consolidated price level. The region or area associated with theconsolidated price level may be include a price column, a quantitycolumn and/or other columns associated with the consolidated pricelevel, for example.

As another example, the expanded consolidated price level interface maybe generated and then displayed automatically. For example, uponreceiving a command to position a cursor in a region or area associatedwith a consolidated price level, the expanded consolidated price levelinterface may be generated and then displayed automatically. As anotherexample, the consolidated price level for which the expandedconsolidated price level interface is displayed may change automaticallywhen the cursor is moved into a region or area associated with adifferent consolidated price level.

As another example, the expanded consolidated price level interface maybe generated and then displayed in response to a cursor being positionedover a consolidated price level for a particular period of time. Thismay happen when the cursor hovers in the same, or approximately thesame, location for the particular time period, for example.Alternatively, this may happen when the cursor remains within an areaassociated with a consolidated price level for the particular period oftime (for example, over a consolidated price displayed in a pricecolumn). The particular period of time may be predetermined orconfigured by a user, for example. For example, the particular period oftime may be predetermined to be 0.25 or 0.5 seconds. As another example,the particular period of time may be configured by a user to be a valuebetween 0.1 and 5.0 seconds. As another example, the particular periodof time may be at least 0.6 seconds.

As another example, the expanded consolidated price level interface maybe generated and then displayed in response to a touch screen input.While a touch screen may not necessarily provide a cursor, a user maytap or otherwise provide an input to the touch screen in a region orarea associated with the consolidated price level and, in response, theexpanded consolidated price level interface may be displayed.

In certain embodiments, the expanded consolidated price level interfaceis displayed in relation to the location of a cursor (or the location ofa touch screen input). For example, a pop-up interface may be displayedapproximately adjacent to the cursor. As another example, the expandedconsolidated price level interface may be displayed under the cursor.

In certain embodiments, the expanded consolidated price level interfaceis displayed in relation to the consolidated price level to which itcorresponds. For example, in a pop-up interface, the expanded pricelevel corresponding to the same price as the consolidated price levelbeing expanded may be displayed approximately adjacent to each other. Asanother example, if a consolidated price level is identified as pricelevel 1000 and includes price levels 995, 996, 997, 998, 999, and 1000,then the expanded consolidated price level interface may be displayedsuch that the expanded price level 1000 is approximately adjacent to thedisplayed consolidated price level 1000.

In certain embodiments, the expanded consolidated price level interfaceis displayed in place of the consolidated price level to which itcorresponds. For example, an in-line interface may replace theconsolidated price level being expanded in the trading interfacedisplay. As another example, if a consolidated price level is identifiedas price level 1000 and includes price levels 995, 996, 997, 998, 999,and 1000, then the expanded consolidated price level interface may bedisplayed such that the expanded price level 1000 is displayed in placeof the consolidated price level 1000 (along with the other expandedprice levels also being displayed).

In certain embodiments, the expanded consolidated price level interfaceis displayed at a predefined location on the screen. For example, theexpanded consolidated price level interface may be displayed in adesignated expanded consolidated price level display area in a tradinginterface. When a new consolidated price level is selected, the newexpanded consolidated price levels may be displayed in that same displayarea. As another example, the predefined location may be a locationseparate from the trading interface, such as a separate, speciallydesignated window.

In certain embodiments, more than one expanded consolidated price levelinterface is displayed. For example, a user may provide a command todisplay an expanded consolidated price level interface for more than oneconsolidated price level. In certain embodiments, when a command isreceived to display an expanded consolidated price level interface, anyother displayed expanded consolidated price level interface is closedand/or removed from display. For example, when a user moves a cursorfrom a region associated with one consolidated price level into a regionassociated with another consolidated price level, a displayed expandedconsolidated price level interface for the first consolidated pricelevel may be hidden or closed and a new expanded consolidated pricelevel interface may be displayed for the second consolidated pricelevel.

In certain embodiments, the expanded consolidated price level interfaceincludes all of the data related to the price levels included in theconsolidated price level being expanded. For example, if a tradinginterface provides the following consolidated price level data:consolidated price level, consolidated bid and ask quantity data, andconsolidated working order data, then the expanded consolidated pricelevel interface would include the individual price levels along with thebid and ask quantity data and the working order data for each of theexpanded price levels.

In certain embodiments, the expanded consolidated price level interfaceincludes a subset of the data related to the price levels included inthe consolidated price level being expanded. For example, the expandedconsolidated price level interface may include one or more of the bidquantity data, ask quantity data, working order data, and the individualprice levels. As another example, an expanded consolidated price levelinterface may include just the bid quantity data and the individualexpanded price levels. As another example, an expanded consolidatedprice level interface may include just the bid and ask quantity data,without any working order data or the individual expanded price levels.As another example, an expanded consolidated price level interface mayinclude working order data, the individual expanded price levels, andonly the bid or ask quantity data if any non-zero values are availablefor any of the individual expanded price levels. As another example, anexpanded consolidated price level interface may include alternativerepresentations of the consolidated data, such as a shortened orabbreviated representation of the price level or quantity data.

In certain embodiments, the expanded consolidated price level interfaceincludes one or more indicators to identify the displayed information asbeing for expanded consolidated price levels. For example, a border maybe displayed around the expanded consolidated price level interface tovisually offset it from other portions of a trading interface. Theborder may be a different thickness and/or color, for example. Asanother example, data displayed in the expanded consolidated price levelinterface may be displayed using different colors (or with differentbackgrounds colors, shading, and/or transparency) from other datadisplayed in a trading interface. Where the trading interface maydisplay bid quantity data with a blue background and ask quantity datawith a red background, the expanded consolidated price level interfacemay display the bid quantity data for the expanded consolidated pricelevels with a light blue background and the ask quantity data with apink background, for example.

In certain embodiments, the expanded consolidated price level interfacedisplays current data for the displayed expanded consolidated pricelevels. For example, the expanded consolidated price level interface mayperiodically update the bid and ask quantity data based on updatedvalues that have been received. As another example, the expandedconsolidated price level interface may reflect changes in working orderdata as updated values are received. In certain embodiments, theexpanded consolidated price level interface displays a fixed snapshot ofthe data for the displayed expanded consolidated price levels. Forexample, while the trading interface may reflect changes in bid and askquantity as updated values are received, the expanded consolidated pricelevel interface may not update its displayed data.

In certain embodiments, a command may be received in order to maintainthe display of the expanded consolidated price level interface so thatit may be interacted with. For example, a user may hold down a key sothat, when moving the cursor from a consolidated price level to theexpanded consolidated price level interface, the expanded consolidatedprice level interface does not move, close, and/or stop being displayedas a consequence of the user moving the cursor to the expandedconsolidated price level interface.

In certain embodiments, an order may be entered using the expandedconsolidated price level interface. For example, an order may be placedby clicking on an expanded price level or in an expanded bid or askquantity column. In certain embodiments, an order may be manipulatedusing the expanded consolidated price level interface. For example, anorder's price may be changed by moving or dragging it from one expandedprice level to another expanded price level (within the same expandedconsolidated price level interface or an expanded consolidated pricelevel interface for a different consolidated price level) or to anotherconsolidated price level. As another example, an order may be cancelled(or the quantity changed) using the expanded consolidated price levelinterface.
